Question

Match the motor molecule to its function

MOLECULES:
-cytoplasmic dynein
-axonemal dynein
-kinesin
-myosin V dimer
-myosin II filament

FUNCTION:
a) processive movement toward microtubule plus end
b) movement along microtubule toward its minus end
c) generates force on actin filaments in a sarcomere.
d) generates force for sliding of flagellar microtubules
e) processive movement toward actin filament plus end.

Answer 1

Cytoplasmic dynein generates force for sliding of flagellar microtubules. Axonemal dynein enables axonemes in cilia and flagella to bend. Kinesin powers the anterograde movement of neurotransmitter vesicles in neurons.

Step-by-step explanation:

Cytoplasmic dynein: Function d) generates force for sliding of flagellar microtubules. It powers the retrograde movement of empty vesicles back to the cell body in neurons.

Axonemal dynein: Function e) processive movement toward actin filament plus end. It enables axonemes in cilia and flagella to bend.

Kinesin: Function a) processive movement toward microtubule plus end. It powers the anterograde movement of neurotransmitter vesicles in neurons from the cell body to nerve endings.

Myosin V dimer: Function e) processive movement toward actin filament plus end.

Myosin II filament: Function c) generates force on actin filaments in a sarcomere. It is involved in muscle movement in animals.
